IPC: H04N1/034
Filed: 1984-01-20
Abstract: PURPOSE:To perform a halftone recording having reproducing capacity from low density to high density without decrease in the resolution by selecting an ink jet head for injecting ink in accordance with a density signal and controlling the volume of ink droplet. CONSTITUTION:A head can inject an ink droplet volume approximately proportional to the pulse length from pulse length tw1 to tw2 of a drive pulse. When th value of input density DI is dense value DIa larger than constant value DT, a high density ink head is selected, ink droplet is injected in pulse length twa corresponding to density level DIa, thereby obtaining corresponding recording density D0a. On the other hand, when the input density level is the value DIb smaller than DT, a low density ink head is selected, ink droplet is injected in pulse length twp corresponding to the density level DIb, thereby obtaining the corresponding recording density Dob. Thus, halftone record from low density DL2 to high density DH1 can be obtained by selecting the head for injecting by the input density level.

Filed: 1993-01-22
Abstract: PURPOSE:To securely recognize a moving body even under environment of illuminance variation or position shift due to vibration by updating a reference image in real time following the variation in illuminance. CONSTITUTION:When N sheets of input images are stored in frame memory 3 from camera 1 under the command of CPU 8, an adding circuit 6 calculates the mean addition of the N sheets of images to make a reference image.

Abstract: PROBLEM TO BE SOLVED: To restrict an area where a sealing material expands to a narrow scope, without using peculiar equipment such as a printer, etc., and further control a scope where the sealing material expands simply and accurately. SOLUTION: In this bare chip sealing method, a first resist layer 5 and a second resist layer 6 are formed thick in a part outside of a sealing region 2, which is later sealed with a sealing material out of a surface of a substrate 1 in which a circuit pattern is formed on the upper face, and an upstanding wall face is formed which is substantially perpendicular to the surface of the substrate 1 and is positioned at the end parts of the resist layers 5, 6 at a boundary between the resist layers 5, 6 and the region 2 to be sealed with a sealing material 8. Since this wall face functions as a bank for clogging the expansion of the sealing material 8 over the sealing region 2, it is possible to simply and accurately control the expansion of the sealing material 8.
